E7.2.6. Accessibility Factor. The accessibility factor
relates the degree that the operation, data, infrastructure, or system needs
to be available from a security perspective. Here, availability concerns are
those that relate to security risks; i.e., non-tolerable operational impacts,
and does not include those that are only performance concerns. Four
alternatives are selectable; reasonable, soon, ASAP, or immediate.

E7.2.6.1. Reasonable. Means that the specific aspect;
i.e., the operation, data, infrastructure, or system, must be available in
reasonable time to avoid operational impacts.

E7.2.6.2. Soon. Means that the specific aspect; i.e., the
operation, data, infrastructure, or system, must be available soon (timely
response) to avoid operational impacts.

E7.2.6.3. ASAP. Means that the specific aspect; i.e., the
operation, data, infrastructure, or system, must be available as soon as
possible (quick response) to avoid operational impacts.

E7.2.6.4. Immediate. Means that the specific aspect; i.e.,
the operation, data, infrastructure, or system, must be available
immediately (on demand) to avoid operational
impacts.
